Plasma
diagnostics are a pool of methods, instruments, and
experimental
techniques used to measure properties of plasma,
such as plasma
components density, distribution function over energy
(temperature), their spatial profiles and dynamics, which enable to derive
plasma parameters.Plasma
diagnostic techniques are also used to observe physical
processes that reveal parameters that characterize plasma. These parameters
include spatial and temporal distributions of constituent particle densities and
temperatures and localized magnitudes of electric and magnetic fields. The
techniques used include those that have applications in other areas of science
and those that have been developed for their unique applications
to plasmas.
